Answer 1

For any request you can check if a user is authenticated or not using this method.

app.get('/some_path',checkAuthentication,function(req,res){     //do something only if user is authenticated }); function checkAuthentication(req,res,next){     if(req.isAuthenticated()){         //req.isAuthenticated() will return true if user is logged in         next();     } else{         res.redirect("/login");     } }
